Will this fitting work to adapt a brake line with 3/8-24 threads to a -4 JIC connection?

This Brakequip adaptor is designed to provide a reliable connection between a 3/8"-24 NF threaded fitting and a No. 4 JIC flare connection, so it should work for that purpose.

got a brake line with 3/8-24 threads on one end and a #4 JIC flare on the other. is this the right adapter?

Answer by: Customer Support on Feb 28, 2026, 6:51 AM

For a connection like that, this adaptor is meant to bridge a 3/8 inch 24 NF threaded fitting over to a No. 4 JIC flare connection, so it matches the thread types you described.
